Perhaps you should try some spelling variations:
wang liang » wang yang
yang guang » yang yang, yan guan, yang liang
child when » child went, child who, children when
child wen » child went, child well, child who
3 longer » _ longer, 2 longer, 3 langer
longer a » longer _
klang 3 » klang 31, klang _, lang 3

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang liang) OR (yang guang)) can ((child wen) OR (child when)) klang 3 longer a ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (yang guang)) can ((child wen) OR (child when)) klang 3 longer a ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (yang guang)) can ((child wen) OR (child when)) klang 3 longer a ;*.
